RECOIIi-LOADING PISTOL.

Application led Junel 16,

T 0 all whom t may concern: Be it known that I, Josnr NrcKLLcnglneer, acitizen of the German Republic, re-

siding at No. 8 of Hauptstrasse, in the city of Oberndorf-on-the-Neckar, Germany, have invented certain new and useful Improvements in Recoil-Loading pistols `(for which I have filed applications initierniany, April 17 1916, Turkey, Sept. 25, 1918, Hungary, Jan. 13, 1920, Poland, March 16, 1920,l Roumania, March 19,- 1920, and CZecho-Slovakia, Dec. 30, 1919-all in the name of lVaifenfabrik Mauser Aktiengesellschaft of Oberndorf-on-the-Neckar) of which the following is a specification. y

My invention relates to a hammer-actuated recoil-loading pistol with yal breechslide guided on the grip-stock and it pertains more particularly to novel improvements in connection with the trigger-mechanism and the safety device.

The object of my invention is to provide a pistol with a combined trigger and safety mechanism of a simple construction and of efficient and reliableoperation. To this end the hammer is provided with a projecting circular rib or flange surrounding or enclosing the actuating nose of the sear andin which a number of notches are provided for the engagement of boththe scar nose and the safety lever. The engaging end of the latter is, for the purpose, bevelled or tapered and the notch co-acting therewith for setting the hammer safe is shaped and arranged `in a manner that when the pistol is set sa-fe"7 by means of the safety lever the hammer is turned backwards by the pressure of the firing pin and thereupon vlocked in lits safety position. IThe arrangementis such that the mechanism operates with perfeet reliability and is protected against the accessy of dirt and grit in a 4simple manner` I have shown in the drawings forming part of this specification, one constructional embodiment of my invention only, but it is to be distinctly understood that my invention is not to be confined to the particular form ofthe improved mechanisms shown by way of illustration.

" In the drawings:

Figure 1 is an elevation of the recoilloading pistol with the improved mechanisms, partly in section and with the hammer uncooked and unlocked.

i921. serial No. 478,210.

Figure 4L is a similar view showing the position of the parts when the hammer is cocked and unlocked,

Figure 5 is a similar view with the hammer locked,

` Figures 6, 7 and 8 are side views and a vertical section of the hammer, respectively,

Figure 9 shows the safety lever, seen from inside and on top, further a side view and a front view of the lever,

Figure 10 shows a side view, a front view and a top view of the scar,

Figure 11 shows the trigger pawl.

The pistol illustrated inthe drawings essentially comprises a grip-stop a with the handle proper, the breech-slide o guided thereon, and the barrel c enclosed to the full of its length by the breech-slide.

In the firing position the barrel c is locked with the breech-slide in a known manner and p after ring the barrel is released or unlocked during the backward movement of the breech-slide, so that the latter runs alone. Units return movement the breech-slide 4is again locked with the barrel. The hammer d `acting on the firing pin c in the well known manner, has a disk-like hub or nave r mounted on a pivot or cross-pins which forms its axis of rotation, and further vhas a circular rib f on said hub or nave, the center of which coincides with the said axis. rThe rib or flange f encircles or surrounds the nose 11 on the scar y' and is cut out to form four circumferential notches of which two, g and h, serve for the reception of the nose i, whilst the other two notches, k and Z, serve for the engagement with the safety lever fm. The sea-r is operated in a known manner by a trigger pawl .0 `pivotally mounted in the triggern, `so that when the hammer is cocked. and a pressure is exerted on the trigger the sear is released from its position in the cocking notch t ofv the-hammer and remains in a released state to allow the hammer to rotate, until the releasing pawl p is moved downwards in the well-known manner by the impact or pressure'of the recoiling breech-slide to disengage the trigger pawl from the scar.

The safety lever m is pivotally mounted in a known manner within the gripstock and safe, that is to say, When the Y safety lever,"

m is moved into lthe position shown in Figure 3, the nose g engagesV inthe' notch 7c of the hammer-and causes the hammer to` turn back from .the position yillustrated in' Figure 1 to 'the position shown in Figure 3, acting at the same time to secure the hammern `the lockedfposition shown in Figure 3,' so

. f ythat a detonation of the cartridge in the barrel cannot occur, even the pistol is accidentally dropped.

Letters Patent is VVIn case rthe pistol is to be put'safejtvith the hammer in cocked position, see Figure '4, thev nose 'g of the safety leverfenga'ges in the notch Z of the hammer, see Figure y5, in order tolock thel latter.` At the same ltime the safety'k lever'supports-thereby thel sear so that the double and consequently an absolutely reliable locking edect'is ensured and the hammer is rigidly held in its locked position. The' notch g of the hammer. is so located that when the parts are in normal position, with the hammer imcocked and unlocked (Fig. 1) the nose of the sear Will project a slight distanceinto said notch,v

which latter is so ,shaped or recessed as to permitthe movement of the hammer due to the pressure exerted'upon it by the iiring- What I claim and desire to secure by the l. In a recoil-loading pistol, the combina-i. tion otra barrel, Aa ygrip-stock, a' breechslide, a'rotatalole hammer having a disklike hub or nave',"a vsear engageable With said hub or nave, and: a safety lever also mounted so as to engage.
